Reset to original state

./vagrant destroy --force && ./vagrant up

.vscode/launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Listen for Xdebug",
            "type": "php",
            "request": "launch",
            "port": 9003,
            "log": true,
            "pathMappings": {
                "/home/vagrant/homestead.test": "/home/chris/code/homestead.test"
            }
        }
    ]
}

Start an ssh session

./vagrant ssh

Create the xdebug log file

sudo touch /var/log/xdebug.log && sudo chmod 777 /var/log/xdebug.log

Create xdebug settings
sudo nano /etc/php/7.4/fpm/conf.d/20-xdebug.ini

zend_extension=xdebug.so
xdebug.mode = debug
xdebug.discover_client_host = true
xdebug.client_host = 192.168.10.1
xdebug.client_port = 9003
xdebug.max_nesting_level = 512

; required for cli debugging but for browser
; could omit and use query string at end
; of url instead XDEBUG_SESSION_START=name
xdebug.start_with_request = yes

; ensure file exists and is writeable
xdebug.log = /var/log/xdebug.log

Switch to cli PHP 7.4

php74

For cli debugging (alias xon=’sudo phpenmod -s cli xdebug’)

xon

After these changes

./vagrant reload --provision

Run phpspec

./vagrant ssh
tail -f /var/log/xdebug.log
project/dir vendor/bin/phpspec run

If vscode will not stop on a breakpoint try re-enabling PHP Debug extension and restarting vscode.

Run ngrok (outside of Homestead) pointing at a configured Homestead site

ngrok http 192.168.10.10:80 -host-header=site.dev

Date and time

by

Updated: 23 February 2024

Create a new object

$date = new DateTime('2000-01-01 20:15:05');

/*var_dump($date);
object(DateTime)#649 (3) {
  ["date"]=>
  string(26) "2000-01-01 20:15:05.000000"
  ["timezone_type"]=>
  int(3)
  ["timezone"]=>
  string(3) "UTC"
}*/

Parse textual datetime description into a Unix timestamp

strtotime(string $dateTimeString, ?int $baseTimestamp = null): int|false

Convert date string to another format

$time = strtotime('11/17/2005');
// var_dump($time);
// int(1132185600)

$newformat = date('d F Y', $time);
// var_dump($newformat);
// string(16) "17 November 2005"

Format a DateTime object as a string

$datetime = new DateTime();
$formatted = $datetime->format('Y-m-d H:i:s');
// var_dump($formatted);
// string(19) "2024-02-23 16:16:24"

Sort multi-dimensional array by value of a DateTime element

$mydates = [
    ['datetime' => new \DateTime('2000-01-03')],
    ['datetime' => new \DateTime('2000-01-01 12:15')],
    ['datetime' => new \DateTime('2000-01-01 12:15:30')]
];
        
usort($mydates, function ($a, $b) {
    return $a['datetime'] < $b['datetime'];
});

/*print_r($mydates);
Array
(
    [0] => Array
        (
            [datetime] => DateTime Object
                (
